    The phytoplankton group’s composition is an excellent indicator of the state of coastal waters. The aim of this study is to explore spatial variability of phytoplankton in shallow coastal areas from different regions (East, Center and West) of the Algerian coast. The quantitative and qualitative study of the phytoplankton population was conducted on samples taken during the 2012-2013 period by the research vessel GRINE BELKACEM. The qualitative results show a significant diversity of diatoms and dinoflagellates, which rank first and second in the total flora (Fr > 50%). This finding is also confirmed quantitatively by the abundance values in both 2013 and 2012 samples which largely exceeds the average value in most other areas of the western region (56%) and slightly exceeding 52% in all central areas which represent an equi-distribution between diatoms and dinoflagellates. The Dinoflagellates contribute significantly to the quantitative richness in the eastern region (>60%). The minimum value of Dia/Dino index, recorded in the eastern region confirms the dominance of the dinoflagellates especially in Skikda (0.31) (Skikda).However, our results reveal the presence, in smaller proportion, of other groups such as the cocolithophoridae and euglenophyceae.

    Journal of Resources and Ecology    2019, 10 (4): 424-431.   DOI: 10.5814/j.issn.1674-764X.2019.04.009

    In recent years, with the rapid development of China’s economy, the coastal environment is facing large pressure. However, the coastal environment pollution has not attracted much attention as air pollution and land water pollution. Based on the data on economic development and marine ecosystem environmental pollution which collected from the National Bureau of Statistics and China’s coastal marine environmental monitoring, the paper analyzes the overall coastal ecosystem environment pollution in China as well as the four sea areas the Bohai Sea, the Yellow Sea, the East China Sea and South China Sea. The paper finds that the coastal marine environment pollution differ in different sea areas, taking the seawater quality, over-standard pollutants, water quality of rivers entering seas and coastal marine environmental disasters, such as red tide as index. Couple of policy suggestions provided based on research findings.
